The bearings you need should be available at any hobby shop that deals in RC cars. Try pm hobbycraft up by big als or modelland on 17 ave sw.
The bearings you need are
7mm x 19mm x 6mm
And
8mm x 19mm x 6mm
You need one of each per mp40. Get the rubber shielded ones. They are quieter than the metal shield type.
Good luck.
